Bitcoin Forum

Its around $270... I looked up Bitcoin in google news and it has a review of  noob who mines .2 BTC a day with it, does anyone here have it?

Lots of people have gotten theirs. Just look around here on the forums.

Any idea on how long shipping is taking from placing the order at this point in time?

To be realistic. At least 3 months but it could easily go to 6

Ridiculous 

**Proudly raises hand**

Just got mine today and up and running on a raspberry PI with minepeon I opened it up with a cool little extra surprise of a free coffee mug (unfortunately not much of a coffee drinker) but thanks BFL totally makes up for my 10 month wait. ;)

People probably aren't mining .2 BTC per day with one now...

Exactly! I'm thinking 1 year.

.2 is about right for 5gh.

Look at the community delivery list http://bfl.ptz.ro/ (http://bfl.ptz.ro/)

The latest received order, as submitted by the community, was ordered on 2012/09/18
Comparing with the current date being 2013/07/02, That's 287 days difference.

So statistically, you are looking at 9 Months delivery time

Try again. It's .12.

Try again. It's 0.11785949.  ;D

Rounding up is for people without 8 decimal places!

Try what. Do you guys even mine? Whats your hasrate and how much bt are you getting a day. Thats what im basing my info on.

Any one of these calculators could have shown you how many BTC per day 5GH/s will generate.

Thanks for the links but they are wrong. If you are mining .1 a day with 5GH you really need to switch your pool or pound your head into  a wall becuase you are getting fucked by your pool. I'm just looking at my own stats plus btc earned a day.

All of a sudden, the math behind bitcoin is wrong!
Someone hacked all the bitcoin calculators today and they no longer work!

You must be a new miner. Welcome to the up-side of variation, aka good luck. Later you'll get to know the down-side, aka bad luck.

I give up. You win the forum and the internet.You obviously are all knowing, and i bow to your intellect.

 I guess my pool is so generous that they give me extra BTCs for my lowly hashrate. So im sorry I am wrong. I will go whip myself in the back for a hour or so as penance.

No im not new. I know variance. Im talking averages here. .2 might be slighlty high, but with a farily good pool .15-.2 should be the norm for 5GH. calculate your own extrapolate to 5gh. tell me you arent close?

I've seen many a 20+ hr block on my pool.

Point is today if you had 5gh on my pool you'd have about .2 btc

Don't feel bad. Most people around here have no idea how Bitcoin works or how to calculate the expected return from a hashing device. You are not alone.
I am sure after a few more months of looking like a complete noob, you will finally start to pick things up and won't make so many embarrassing posts.
Just hang in there!

You probably talking about one those upgraded units? I have some that do about 0.186.

That wouldn't be the expected return of 5GH/s though. That would be the expected return of about 7.9GH/s.
The amazing part of this is that so many people are totally unaware of the most elementary calculation of Bitcoin mining. The expected return of a hash rate at a given difficulty.

Not at 5GH indeed.
You could still say that a (what we usually call Jalapeno) could do 0.2/day. It would take an upgraded unit and a bit of luck. A firmware tweak could raise the hash even more.

None of my units (as they came) can hash above 7.95GH though...

A Jalapeno could do 50 BTC in a day. In fact, it could do 50 BTC in an hour just by getting lucky and finding 2 blocks in a row. It is merely unlikely to do so. But that is the nature of probability.

The OP was about the stock 5GH/s miner from BFL for $274.  With a firmware upgrade ($100 if they still offering it?) and good chips, it could do more. With enhanced cooling and overclocking, probably even more. But if he buys a 5GH/s unit with no upgrade, it might only do 5GH/s reliably.

Hey, a 5870 could do 50BTC this way :)

(No idea about the upgrade offer)

Let us put it this way then:
A device hashing at 5GH can't do 0.2 BTC/day.
A Jalapeno can.

The fastest Jalapeno reported on these forums with the upgrade and firmware tweaked is 8.2GH/s. That would clock in at 0.19328956 per day.
The stock Jala can't get close to that anymore now that BFL is binning their chips.

In any case, the order the OP was talking about wouldn't get close.

The fastest one does 9.2 (8.6 previously).

I'm one of the 'lucky' ones who had two early September 2012 orders. I opted for the upgraded versions. Each running >7.4Gh/s, took the cases off and they run 10C cooler with the fan blowing down on the heatsink. Considering flashing them but would it be worth the risk to gain ~10%?

I'm not flashing mine.  If I was running under 5GH/s maybe.  But not at a stock 7.1 at temperature.

The stock fan on the Jally looks a bit....what shall I say?  Sub-optimal. 

Can someone list the maker and model number of the stock fan?  I'm pretty sure a better fan would cool better while being quieter at the same time.

I thought exactly the same, I was prepared to buy a bunch of Delta fans or whatever...
However, the stock fan does its job very well. As long as you place them in a proper ventilated place you won't get in any trouble.
You can barely hear the fan itself, rather the woosh of the air passing through the case.

I have seven 7GH Jalapenos still in the case reaching at most 40C when is hot outside, and two stripped with the fans blowing down hovering about 35C, while the aluminium radiator is barely warm to touch, almost cold...

They do need some ventilation, an open window or something, but I think that much is obvious.

Mine runs at around 41C, no HW errors, still in the case as shipped. Not hot enough for me to mess with, but maybe get bold here in a week or some and try and flash mine.

True...BTCGuild tells me I'm usually getting .25 to .3 BTC per day with two.  It had gone as low as .2, but maybe the pool hit a run of bad luck.
